Voice pitch is an essential feature for speech understanding. Envelope following responses (EFRs) are a useful EEG measure to infer the encoding of voice pitch and can be elicited by band-limited speech to assess the processing of voice pitch in a frequency-specific manner.

Although research demonstrates that autistic children are at risk of poor sleep quality, very little is known about sleep quality and its impact on quality of life in autistic adults.

The uncinate fasciculus is a white matter tract that may facilitate emotion regulation by carrying connections from the prefrontal cortex to regions of the temporal lobe, including the amygdala. Depression and anxiety are associated with reduced uncinate fasciculus fractional anisotropy (FA) – a diffusion tensor imaging measure related to white matter integrity.

Adults with Down syndrome (DS) are predisposed to Alzheimer’s disease (AD) and reveal early amyloid beta (Aβ) pathology in the brain. Positron emission tomography (PET) provides an in vivo measure of Aβ throughout the AD continuum. Due to the high prevalence of AD in DS, there is need for longitudinal imaging studies of Aβ to better characterize the natural history of Aβ accumulation, which will aid in the staging of this population for clinical trials aimed at AD treatment and prevention.

Over the last decade, multiple studies have highlighted the essential role of gut microbiota in normal infant development. However, the sensitive periods during which gut bacteria are established and become associated with physical growth and maturation of the brain are still poorly defined. This study tracked the assembly of the intestinal microbiota during the initial nursing period, and changes in community structure after transitioning to solid food in infant rhesus monkeys (Macaca mulatta).

Hearing impairment (HI) is an epidemic affecting over 1.5 billion individuals of all ages. Globally, unaddressed HI causes losses of ~US$1 trillion each year. Addressing HI requires early detection which current hearing screening tools are inadept at doing efficiently. Specifically, current hearing screening tools can either only index the sensory cells in the inner ear or require measurement of brainstem electroencephalography (EEG) to index the sensory cells and the auditory nerve which require additional resources.

Alzheimer's disease is characterized by accumulation of amyloid and neurofibrillary tangles, and this pathology can be detected using neuroimaging or fluid biomarkers prior to the development of dementia. The Alzheimer's disease process also involves neurodegeneration which eventually leads to cognitive decline and dementia, however typical approaches for measuring neurodegeneration (such as T1-weighted imaging), may not be sensitive to neurodegeneration in the asymptomatic disease stage.
